detailed description

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

An embodiment of the present invention provides a cross-network communication method. Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a first embodiment of the cross-network communication method of the present invention.

In this embodiment, the cross-network communication method includes the following steps:

Step S10: when there is a cross-network communication service in the local cross-network component, obtain the service type corresponding to the cross-network communication service;

It should be noted that the execution subject of the cross-network communication method provided in this embodiment may be a privatized deployed network (hereinafter referred to as the local network), and the network communicates with other one or more A network (that is, an external network) for communication and interaction. Before executing this embodiment, it is necessary to pre-deploy the above-mentioned cross-network component in the local network and external network participating in the interaction. This component can be a specific component or service (such as message queue MQ) that receives cross-network communication services, or are other components or services that perform the same or similar functions.

It should be understood that the above cross-network communication service may be a communication service that needs to be transferred and coordinated between the local network and the external network. In this embodiment, the service types of the cross-network communication service include internal and external cross-network communication services and external and internal cross-network communication services. Among them, the internal and external cross-network communication services can be transmitted from the local network to the external network and processed by the external network, and the external and internal cross-network communication services can be transmitted from the external network to the local network and processed by the local network business.

Step S20: When the service type is an internal and external cross-network communication service, determine whether a cross-network connection has been established with the target external network;

It should be noted that the cross-network connection is a cross-network communication connection established in advance between the local network and the external network. In practical applications, the connection can be established based on the TCP protocol. The target external network may be the external network pointed to by the current cross-network communication service to be processed. For the local network, there may be one or more external networks, which is not limited in this embodiment.

It should be understood that if the cross-network connection has been established, it means that the local network and the external network have previously established a communication connection based on a custom handshake protocol; otherwise, it means that the cross-network connection needs to be established first.

As a way to determine the target external network, a network identification mark can be added to the cross-network communication service in advance. The network identification mark can represent the uniqueness of the network and is used to determine the external network to which the cross-network communication service is directed. Specifically, when the local network receives the cross-network communication service, it may first obtain the network identification carried in the cross-network communication service; and then determine the target external network corresponding to the cross-network communication service according to the network identification .

In specific implementation, when the local network determines that the current inter-network communication service is an internal and external inter-network communication service according to the service type, and determines the target external network according to the network identification, it can further judge whether the above-mentioned inter-network communication service has been established with the target external network. network connection.

Step S30: If yes, push the cross-network communication service to the target external network through the cross-network connection, so that the target external network processes the cross-network communication service through its own cross-network component.

It should be understood that, in the case that the local network and the target external network have established a cross-network connection, the local network can push the cross-network communication service to the target external network through the cross-network connection, and similarly, because the external network and the local The network is the same, the above cross-network components are pre-deployed, so the local network pushes the above-mentioned internal and external cross-network communication services to the target external network through the above-mentioned cross-network connection, and the (self) cross-network components in the target external network respond to the cross-network communication services Processing, so as to achieve communication between cross-network.

In this embodiment, when there is a cross-network communication service in the local cross-network component, the service type corresponding to the cross-network communication service is obtained; when the service type is an internal and external cross-network communication service, it is judged whether a cross-network connection has been established with the target external network; If so, push the cross-network communication service to the target external network through the cross-network connection, so that the target external network processes the cross-network communication service through its own cross-network component. Since cross-network components for processing cross-network services are deployed in both the local network and the foreign network in this embodiment, cross-network communication services can be logically isolated from local communication services to ensure data security and information security. In addition, this embodiment transmits and processes communication services through cross-network components and cross-network connections, providing a safe and effective way for the interaction between privatized deployed networks.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a second embodiment of the cross-network communication method of the present invention.

Based on the first embodiment above, in this embodiment, before the step S10, it also includes:

Step S01: Obtain the session information of the session to which the communication service to be processed in the local cross-network component belongs;

It should be noted that the communication services to be processed in this embodiment may include cross-network communication services and intranet communication services. The so-called cross-network communication service refers to the communication service between different networks, including the internal and external cross-network communication service and the external and internal cross-network communication service. The so-called intranet communication service refers to the communication service within the local network. These communication services do not need to be coordinated with the external network, and the entire communication service is processed within the local network.

It should be understood that in the field of instant messaging, chat communication services are mostly presented in the form of sessions. In this embodiment, the above session information may include names of session participants, networks they belong to, and session types. Among them, the session type can include local single-person session (single chat), local multi-person session (group chat), cross-network single chat, cross-network group chat, etc. Different types of conversation types can be used to determine whether the communication service to be processed belongs to the internal Network communication business is also one of the basis of cross-network communication business.

Step S02: Determine whether the communication service to be processed belongs to an inter-network communication service according to the session information.

In specific implementation, after knowing the session information of the session (including single-person session or multi-person session) to which the communication service to be processed belongs, it can be judged according to the session information whether the service belongs to the cross-network communication service.

Specifically, in order to improve the judgment efficiency and accuracy, in this embodiment, the local network may first determine the network identifier of the network to which each session participant belongs according to the session information, and then judge whether the communication service to be processed is It belongs to cross-network communication business.

As an implementation, the local network can determine whether there are different network identifiers among the network identifiers; if it exists, it is determined that the communication service to be processed belongs to a cross-network communication service; if it does not exist, it is determined that the communication service to be processed The communication service does not belong to the cross-network communication service.

It should be understood that a single-person session includes an intranet single-person session and an inter-network single-person session, and a manner of distinguishing them may be determined by determining network identifiers of networks used by both parties participating in the session. Usually, in a single-person session on the intranet, the two parties participating in the session use the same network, and their corresponding network identifiers are also the same. At this time, it can be determined that the communication service to be processed does not belong to the cross-network communication service but belongs to the intranet communication. On the contrary, if the network identifiers are different, it indicates that the two parties participating in the session are not using the same network. At this time, it can be determined that the communication service to be processed belongs to the cross-network communication service. Wherein, the network identifier may be tag information representing the uniqueness of the network.

For a multi-person session, in this embodiment, when the session type is a multi-person session, the creation entry information of the multi-person session can be acquired, and then judge whether the pending communication service belongs to cross-network communication according to the creation entry information. way of business. Specifically, the session type of the session may be determined according to the session information, and when the session type is a multi-person session, the creation entry information of the session is obtained, and the communication service to be processed is judged according to the creation entry information Whether it belongs to cross-network communication business.

It should be understood that the intranet multi-person session does not involve external personnel, while the cross-network multi-person session will involve external personnel. In this embodiment, the client corresponding to the local network is creating the intranet multi-person session and the cross-network multi-person session , the session creation entrances are different, that is, the page controls or buttons that the user clicks on the client interface to create intranet group chats and cross-network group chats are different. Therefore, in this embodiment, by obtaining the creation entry information of the multi-person session, and then according to the creation entry information, it is possible to distinguish whether the pending communication service initiated by the client belongs to the cross-network communication service or the intranet communication service.

Of course, in a multi-person conversation scenario, it is also possible to first determine the network identifiers of the networks to which the participants of the multi-person conversation belong according to the session information of the multi-person conversation, and then judge the communication service to be processed according to whether these network identifiers are consistent. Whether it belongs to the cross-network communication service; if the network identifiers are the same, it can be determined that the pending communication service does not belong to the cross-network communication service (that is, belongs to the intranet multi-person session); otherwise, if there are different network identifiers among these network identifiers , indicating that the networks used by the session participants are not the same, and at this point it can be determined that the communication service to be processed belongs to a cross-network communication service (that is, belongs to a cross-network multi-person session).

Further, when the communication service to be processed does not belong to the cross-network communication service, the local network determines that the communication service to be processed belongs to the intranet communication service; then obtains the service attribute of the communication service to be processed, and according to the service attribute The communication service to be processed is routed to a corresponding intranet service for processing.

Wherein, the above-mentioned intranet service is a service deployed in a local network, and the above-mentioned service attribute may refer to a specified characteristic of a certain telecommunication service, which is mostly used in the communication field.

It should be understood that the intranet communication service is the communication service related to the inside of the local network. When the received communication service is an intranet communication service, the local network can route the pending communication service to the corresponding Intranet services for processing.

In this embodiment, by acquiring the session information of the session to which the communication service to be processed belongs, the service type of the communication service to be processed can be accurately distinguished, and then processed in a targeted manner, thereby improving the processing efficiency of the communication service.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a third embodiment of a cross-network communication method according to the present invention.

Based on the above-mentioned embodiments, in this embodiment, after the step S20, the method further includes a process of cross-network connection when no connection is established with the target external network, specifically including:

Step S40: If not, obtain the network access identifier and communication encryption identifier corresponding to the target external network;

It should be understood that if a cross-network connection has not been established between the local network and the target external network, the local network can establish a cross-network connection through the network access identifier and communication encryption identifier shared by the administrator of the target external network with the administrator of the local network in advance. network connection.

It should be noted that the network access identifier may include: an IP address and a port number, and the communication encryption identifier includes a public key of an asymmetric encryption algorithm, such as an RSA public key.

Step S50: Generate a connection request according to the network access identifier, and encrypt the connection request through the communication encryption identifier to obtain an encrypted connection request;

In specific implementation, the local network can initiate a connection request to the target external network through the above-mentioned network access identifier, and then encrypt the request through the communication encryption identifier provided by the target external network to obtain an encrypted connection request, and then send the encrypted connection request to the target external network network.

Step S60: Send the encrypted connection request to the target external network, so that the target external network establishes an inter-network connection after the encrypted connection request is verified successfully.

It should be noted that for the external network, when an encrypted connection request is received, the request can be decrypted through the communication decryption identifier. If the decryption is passed, it indicates that the verification is successful, and the subsequent operation of establishing a cross-network connection can be performed.

Of course, in practical applications, the local network can serve as both the initiator of the cross-network connection request and the receiver of the cross-network connection request, so the cross-network communication method provided in this embodiment also includes:

Step S1: Obtain the communication decryption identifier corresponding to the cross-network connection request when receiving the cross-network connection request initiated by the target external network;

Step S2: Verifying the cross-network connection request through the communication decryption identifier;

It should be understood that the above-mentioned communication decryption identifier may be a private key corresponding to the communication encryption identifier, such as an RSA private key. Through the communication decryption identifier, when the local network receives the cross-network connection request from the external network, it will verify the cross-network connection request through the communication decryption identifier corresponding to the communication encryption identifier previously shared with the external network.

Step S3: When the verification is passed, a selection prompt for establishing a cross-network connection is displayed on the preset interactive interface;

In the specific implementation, the local network decrypts the cross-network connection request through the communication decryption identifier. If the decryption is passed, a selection prompt for establishing a cross-network connection will be displayed on the preset interactive interface, such as the network management used by the administrator of the local network. A window pops up on the client page, prompting the administrator to choose "Agree" or "Reject" the cross-network connection request initiated by the target external network.

Step S4: Establishing a cross-network connection with the external network when a confirmation instruction prompted for input based on the selection is detected.

In a specific implementation, when the administrator chooses to agree, that is, when the local network detects a confirmation instruction based on the prompt input based on the selection, a cross-network connection is established with the external network. On the contrary, when the administrator chooses to refuse, that is, when the local network detects the rejection instruction input based on the selection prompt, the establishment of the cross-network connection with the external network is stopped.

Furthermore, if the verification of the cross-network connection request by the local network fails, it means that the source of the cross-network connection request cannot be identified. At this time, the cross-network connection request needs to be discarded, and no interactive response needs to be made on the interactive interface.

In addition, it should be emphasized that after the communication encryption identifier shared by the local network has been used by the corresponding external network, if there is a new external network that needs to create a new cross-network connection with the local network, the network management of the local network is required. The member provides the network access identification and the new communication encryption identification to the new external network, and then creates a new cross-network connection again according to the security mechanism of the above handshake (that is, the above steps S1-S4).

Based on the above-mentioned embodiments, a fourth embodiment of the cross-network communication method of the present invention is proposed.

In this embodiment, the local cross-network component is a message queue MQ, and correspondingly, the cross-network communication method further includes the following steps:

Step S1': When receiving a request for creating a cross-network session initiated by a client, generate a cross-network session creation event according to the request for creating a cross-network session;

It should be noted that the request for creating a cross-network session is a communication service request for creating a cross-network single chat or a cross-network group chat. When the local network receives the request, the internal service cloud first processes the cross-network group building logic. After the processing is completed, a cross-network session creation event is generated and a group building success message is sent to the above-mentioned client.

Step S2': posting the cross-network session creation event to the message queue for consumption;

In a specific implementation, the local network delivers the generated cross-network session creation event to the message queue MQ for consumption.

Step S3': when consuming the cross-network session creation event, push the cross-network session creation event to the target external network through the established cross-network connection, so that the target external network The session creation event is processed to complete the creation of the cross-network session.

It should be understood that when the message queue MQ deployed in the local network consumes the above-mentioned cross-network session creation event, since a cross-network connection has been established between the local network and the target external network, the local network can directly pass through the cross-network session at this time. The network connection pushes the cross-network session creation event to the target external network. The external agent deployed in the target external network delivers the event to its own cross-network component (ie, its own message queue) for consumption. During the consumption process, the internal agent in the target external network will call the business service, and the service cloud in the target external network will process the cross-cloud group building logic, and push the session creation message to the client in the target external network to complete the cross-network session of the creation.

Further, after the creation of the inter-network session is completed, users in the inter-network can chat through them. In this embodiment, the local network may post the session message sent by the target external network to the message queue for consumption, so as to push the session message to the corresponding session client.

As an implementation method, when a client in the target external network sends a cross-cloud group message (session message), the service cloud in the target external network will process the group chat logic of this cloud and deliver the group message event to the client in the target external network In the internal agent, the internal agent processes the delivery logic of the group message, delivers the group message event to its own message queue (MQ) for business message consumption, and passes it to the external agent in the target external network, and the external agent passes the cross-cloud group message through Cross-network connections are sent to the local network.

The external agent in the local network delivers the cross-cloud group message (session message) in the target external network to the local message queue (MQ) for consumption, and the internal agent in the local network processes the call logic and sends the group chat message to the local network The service cloud, which pushes session message notifications to clients in the local network, and then completes cross-network communication.

Referring to FIG. 4, FIG. 4 is a structural block diagram of the first embodiment of the communication network of the present invention.

As shown in FIG. 4 , the embodiment of the present invention proposes a communication network 10, in which an internal agent 101, a cross-network component 102 and an external agent 103 are deployed;

The internal agent 101 is configured to acquire the service type corresponding to the cross-network communication service when receiving the cross-network communication service;

The internal agent 101 is further configured to deliver the cross-network communication service to the cross-network component when the service type is an internal and external cross-network communication service;

The cross-network component 102 is configured to send the cross-network communication service to the external agent;

The external agent 103 is used to determine whether an inter-network connection has been established with the target external network corresponding to the inter-network communication service;

The external agent 103 is further configured to push the cross-network communication service to the target external network through the cross-network connection, so that the target external network can send the cross-network communication service to the cross-network component through its own cross-network component. Communication business is processed.

It should be noted that the communication network 10 provided in this embodiment may be a privatized deployment network or a private cloud, and the network is provided with an internal agent 101 , a cross-network component 102 and an external agent 103 . As shown in FIG. 5 , FIG. 5 is a schematic diagram of the system architecture of the communication network in the first embodiment of the communication network of the present invention. In FIG. 5 , the system architecture of the first network, the second network and more networks is the same as that of the communication network 10 provided in this embodiment, including an internal agent 101 , a cross-network component 102 and an external agent 103 . It also includes several access gateways and different types of databases (MySQL, MongoDB, Redis, ES and OSS). While the first network is the home network, the second and further networks are external. When the local network communicates with the external network across the network, the internal agent 101, the cross-network component 102 and the external agent 103 cooperate with each other to complete the processing of the communication service.

Among them, the internal agent 101 is used to connect to communication services within the network, such as internal single chat, group chat, and personnel management services. When the internal agent 101 receives a service related to the cloud, it delivers the service to the internal processing, and is also responsible for processing the communication service from the outside. The cross-network component 102 may be a specific component or service (such as message queue MQ) that receives cross-cloud/cross-network communication services, or other components or services that can achieve the same or similar functions. The external agent 103 is used to deliver the communication services involving cross-cloud/cross-network in the communication business inside the private cloud to the cross-network components in the other party's network through the external agent in the other party's network, and at the same time pass the other party's network through the other party's external The cross-cloud communication service pushed by the agent is delivered to the cross-network component inside the cloud, and after consumption, it is routed to different services through the internal agent 101 according to the business attributes.
